When Shelby Blackstock and his wife, Marissa Branch, shared the first photos of their newborn son, Shelby Archer McEntire Blackstock, on October 21, 2026, the update included a short hospital clip of the infant resting under a blue bilirubin light.
Called Archie by his parents, the baby boy had already been home for a couple of weeks before the 36-year-old racing driver and his 33-year-old wife announced his arrival on Instagram Stories. His birth gave 71-year-old Reba McEntire her first biological grandchild after the young couple spent nearly four years navigating infertility, grueling hormone regimens, and pregnancy loss.
Their hope of starting a family began shortly after their February 2022 wedding at Walt Disney World, where they held ceremonies at Epcot and the Magic Kingdom. After more than a year of trying to conceive naturally without ever seeing a positive test, they consulted top obstetricians in Nashville and began medicated cycles.
By November 2023, when those treatments still had not worked, Marissa publicly praised Shelby for keeping his optimism steady through every negative result. Over the next year and a half, the couple prepared to move into full in vitro fertilization.
When Marissa began her first round of IVF medications at five o’clock one evening in July 2025, the physical toll hit within hours. She woke up the next morning with a flared spinal disc, severe nausea, hot and cold flashes, and night sweats heavy enough that she had to sleep on a towel while struggling to keep water down.
Throughout those appointments and daily injections, McEntire stayed quietly in their corner away from the public eye, checking in on her only biological son and daughter-in-law as they worked toward an embryo transfer.
Late in 2025, the family went through a sudden swing between grief and hope. The day after Marissa’s father passed away in November, she woke up on Thanksgiving morning and saw two pink lines on a pregnancy test for the first time in three years.
That relief lasted only a few days before the pregnancy ended in an early loss in December. Even while mourning both her father and the baby, Marissa told followers who had been praying for them that the brief pregnancy proved her body was capable of carrying a child.
A subsequent transfer succeeded early in 2026. By February, Marissa was sharing updates about early pregnancy symptoms, and in April the couple returned to Walt Disney World to announce that their baby boy was due in October.
In July 2026, friends and family gathered for a music-themed baby shower billed as Archer’s “Welcome To The World” Tour. Guests signed a custom vinyl record plaque labeled “Archie Blackstock: A Star is Born,” where the future grandmother wrote in the bottom left corner, “We’re gonna have so much fun!” and signed it “Grandma Reba”.
When Archie arrived that autumn, his first seven days required extra medical attention before the couple could settle in at home. Alongside a photo of Marissa nursing him in a hospital bed, the new parents posted footage of their newborn wearing protective eye coverings under a phototherapy lamp used to treat infant jaundice.
Shelby noted on the slide that his son “had a rough first week, but at least he had the look down”. Once doctors cleared Archie to leave the hospital unit, the couple kept the news private for a few weeks so they could adjust to life at home without phones or public attention in the way.
In their October 21 statement, they wrote that after everything it had taken to reach that point, they finally got to call themselves Mom and Dad and had been keeping those early weeks just for the three of them.
For McEntire, the infant resting safely at home carries her middle name into a new generation after years of watching her son and daughter-in-law fight for every step toward the delivery room.
